Title: High power y-junction h-plane circulator for microwave trans mission
IPC: H01P1/39
Filed: 1973-11-14
Abstract: 1420050 Microwave circulators; permanent magnets THOMSON-CSF 14 Nov 1973 [17 Nov 1972] 52921/73 Headings H1W and H1P Operation of an X-band high-power, Y- junction, H-plane circulator, at temperatures between -40C. and +85C. is secured by using for the ferrimagnetic element a material having a spin-wave linewidth below 10 oersteds, and a biasing field which is capable of saturating the material, stronger than the field associated with minimum critical power and close to the limit beyond which non-linear effects are negligible. "Critical power" is defined as the input power above which losses between coupled ports, begin to rise rapidly (see Fig. 1, not shown) and, as shown in Fig. 2, it varies with the applied magnetic field. A field is chosen above the value M corresponding to minimum critical power and close to the limiting field H L . Examples of materials suitable for the ferrimagnetic elements are: Y 3-3x Gd 3x Fe 5 O 12  (x = 0À310%), Y 3 Fe 5-5y Al 5y O 12  (y=0À07410%). The circulator (Figs. 3, 4, 5, not shown) is of conventional construction using ferrite elements mounted on aluminium discs and samariumcobalt permanent magnets.

Title: Improvements in or relating to adaptive systems
IPC: G06V30/194
Filed: 1964-12-31
Abstract: 1,066,279. Adaptive circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 31, 1964 [Dec. 31, 1963], No. 53003/64. Heading G4R. An adaptive system for producing from input information desired output information comprises circuits (24-1 to 24-Z, Fig. 1, not shown), responsive to input data (el-en) and circuits (46-1 to 46-Z) which compare the actual outputs with the desired outputs on leads (48-1 to 48-Z) and act on circuits (24-1 to 24-Z) to modify them so as to produce the desired output information. The input signals (el-en) may represent the condition of a matrix of detection cells sensing a pattern to be identified. In circuits (24-1 to 24-Z) each signal is inverted and applied in true form to one end of a potentiometer and in inverse form to the other end. A moving slide on the potentiometer picks off a proportion of the difference voltage and the resulting signals for all inputs are added. The highest signal is found by comparing the signals with a falling ramp voltage. The first to become more than the ramp gives an output which passes through an Or gate (34) and sets a single-shot circuit (36). This briefly opens gates (40-1 to 40-Z) to allow the first occurring pulse to pass to a corresponding flip-flop (40-1 to 40-Z). If other signals occur within the set period of single-shot (36) the corresponding flip-flops are also set. Circuits (46-1 to 46-Z) compare the outputs of these flip-flops with the desired outputs by a gating arrangement to determine whether increase or decrease is needed in the weighting of those input signals which are present i.e. " 1." For this purpose the potentiometer of each input signal (el-en) is controllable by a unit amount by an actuator having " increase " and " decrease " inputs coming from pairs of gates controlled by the corresponding input signal (e1-ez) and the output of the circuits (46-1 &c.) on leads (50-1 &c. or 52-1 &c.).

Title: Improvements in or relating to combined mowing and crop conditioning agricultural machines
IPC: A01D43/10
Filed: 1965-12-20
Abstract: 1,123,218. Crop cutting and conditioning machines. INTERNATIONAL HARVESTER CO. 20 Dec., 1965 [15 March, 1965], No. 53785/65. Heading A1F. A machine for cutting and conditioning crop has a reciprocating mower bar 23 feeding cut crop between a pair of conditioning rollers 32 and 33 and is characterized by a bar 200 placed above and in front of the mower and arranged to bend the crop forwardly before it is cut by the mower whereby the cut crop is positioned for feeding between the rollers. The bar 200 is carried by a linkage 205 which is adjustable to alter both the forward projection and the height above the ground of the bar. The roller 32 is carried by a bell-crank 61, 63 which is pivoted to the machine frame at 64 and is connected to a lever 70 adapted to be moved upon rotation of a shaft 73. This shaft is connected to ground wheels carried by cranks 76 and 182 whereby, on rotation of the shaft 73 by a hydraulic ram, the cranks move to lift the machine away from the ground, and, simultaneously, the lever 70 moves to displace the roller 32 from the roller 33. Biasing springs return the parts to the operative position on contraction of the ram. Rotation of the shaft 73 also disconnects a belt which drives the rollers from a gearbox 157 driven from the power take-off of a tractor. The crop discharged from the rollers passes under a deflector plate 190 having a fixed side plate 192 and an adjustable side plate 191 so that the crop can be discharged from the machine in a windrow.

In a motor vehicle having front and rear wheels 2, 2<SP>1</SP> and 3, 3<SP>1</SP> steered by respective pairs of hydraulic rams 9, 9<SP>1</SP> and 10, 10<SP>1</SP> controlled by a steering valve 22 operable by the driver, a selector valve 27 for isolating the rams 9, 9<SP>1</SP> when it is desired to steer the rear wheels only is interlocked with a high/low range transmission control lever 50 to prevent use of four wheel steering and a high range transmission ratio at the same time. Further interlock means 54 are provided for preventing isolation of the rams 9, 9<SP>1</SP> unless the front wheels 2, 2<SP>1</SP> are in the straightahead position. The steering valve 22 is actuated from a steering wheel 19 through steering gear 19a, and a follow-up linkage 24, 25 connects the valve housing and a rear wheel track rod 13. Fluid from a pressure source comprising an engine-driven pump 20, unloading valve 20a and a reservoir 32 is directed by the steering valve 22 to the selector valve 27 which either supplies both pairs of rams 9, 9<SP>1</SP> and 10, 10<SP>1</SP> in series or supplies the rams 10, 10<SP>1</SP> only, the rams 9, 9<SP>1</SP> being hydraulically locked. The transmission control lever 50 is linked through a rod 51 to a gear-box 15 connecting an engine 14 to the front and rear wheels through shafts 16 and differential gears 17, 18. Lost motion connecting means 53 between the selector valve 27 and a crank arm 52 on the lever 50 is arranged such that movement of the selector valve to the four wheel steering position is either prevented if the lever 50 occupies the high range position or causes simultaneous movement of the lever out of the high range position. The interlock means 54 is actuated by a front wheel track rod 12 and prevents both movement of the selector valve 27 from the four wheel steering position and movement of the lever 50 into the high range position if the front wheels occupy other than the straight-ahead position. In another embodiment, Fig. 2 (not shown), both the front and the rear wheels are separately steerable. In a further embodiment, Fig. 3 (not shown), follow up is provided by metering the fluid flow to the steering rams and provision is made for crabwise steering of the front and rear wheels.

Abstract: 1531229 Radiography EMI Ltd 9 Dec 1975 [19 Dec 1974] 55060/74 Heading H4F A radiological examination apparatus comprises a source 1 of a fan-shaped beam of X-rays which irradiate a body 4 and the transmitted portion of which is detected by detectors 3 signals from which are used to construct a representation of the absorption distribution over a slice of the object 4, the source and detector being mounted on a yoke 17 which is laterally scanned back and forth along rails 16 while the source and detectors are simultaneously orbited in a continuous fashion about axis 10 at a rate of the order of 3 degrees per lateral scan. The signals so claimed are processed ignoring the orbital motion, i.e. a particular beam path in the fan-shaped beam is regarded as being translated but not rotated so as to give effectively a set of parallel ray paths. The signals are processed using a convolution technique which inherently gives lower weighting to data more remote from the point under consideration at any time, thereby supporting the assumption that the rays form parallel sets. When the processed data are stored the rotation is taken into account in allocating the store positions.
